The report to Congress that has recently been prepared in response to a directive by the Congress to examine the need for, and desirability of, uniformity in maximum truck length and weight limits throughout the United States is summarized. Several alternative changes to federal limits on truck length and weight are investigated, and the impacts that these changes would have on truck productivity, modal diversion, freight costs, pavement and bridge costs, safety, energy, air quality, and noise are estimated. Also estimated was the present value of forecast cumulative changes in transportation and highway system costs. It was found that increases in truck length and weight limits within a substantial range provide sufficient transportation cost savings to pay for damage done to the highway system under changes in the limites. However, if limits are increased without a corresponding increase in highway system expenditures, then the condition of pavements and bridges in the United States would deteriorate, which would, in turn, affect the motor vehicle operating costs, travel speeds, and circuity experienced by highway users.
